Letters Patent No. 87 ,684, dated Ma/rch 9, 1869.-

IMPROVED BRUSH-HANDLE.

The Schedule referred to in these Letters Patent and making pan of thesame.

To all whom it may concern.-

hereby declare that the following is a full, clear, and

exact description of the same, reference being had to the accompanyingdrawings, making a portion of this specification, in which- Figure 1 isa side view of a brush made according to my invention.

Figure 2 is a side view and partial section of the same,'taken at rightangles to fig. 1.

Figures 3 and 4 are detached views, indicating certain modifications ofthe sa e.

Similar let 0 refere e indicate. corresponding parts in all the figures.

This invention relates to that variety of brushes which have their headsmade adjustable at difierent angles to their handles, as is desirable inscrubbing or cleaning walls, windows, ceilings, and the'like.

Theinvention consists in so combining two interlocking plates, and atightening-screw and nut, with the brush-head, and'the staff, or handle,of the same, that the head may be readily adjusted, and firmly securedat any desired angle to the staff, or handle, in

such manner that paint, whitewash, or other pigment will not penetrate,to clog the interlocking parts.

To enable others to understand the nature and construction of myinvention, I will proceed to describe it withgeference to the drawings.

A represents the staff, or handle of the brush, to one end of which, ina position longitudinal thereto, is firmly secured a metallic plate, B,upon one side of which is formed a circular series of spurs, or teeth,a, pointing radially inward; the plate B being furthermore provided, 'atthe same side with its teeth'a', with a cylindrical-threaded spur,or'screw, A, having upon its outer end a nut, B and the purpose of whichwill presently herein appear.

The brush-head B may be of rectangular or other any appropriate manner.

Secured to the back of the head B, in a position at right anglesthereto, is a metallic plate,'F, upon one side of which is a circularseriesof spurs, or teeth, I), pointing radially outward, andcorresponding to the teeth a of the plate B. The two plates being placedtogether, with the teeth of one situated in the spaces between the teethof the other, with the screw A* F, at the centre'of its circular seriesofteeth I), just described, the not B* is screwed upon the screw A,tightly against the plate F, and by clamping the plates, interlocked, asit were, by their teeth, a b, snugly together, insures the retention of.the head in a fixed position upon the staff orhandle, and theperipheries of the plates B and F fitting closely together, excludebecoming clogged.

In order to change the angle of the head with reference to the staff, orhandle, it is only necessary to unscrew the nut Bt, so that the teeth onone plate may be brought clear of those on the other, which being done,the head is turned around the axis of the screw fixed thereat by simplytightening the nut upon the screw, as hereinbefore explained.

What I claim as my invention, and desire to secure by Letters Patent,is- V The plates B F, constructed, the one with internal and the otherwith external radial teeth, fitting one within the other, and clampedtogether, in such manner as to exclude the paint or other pigment fromsaid teeth, substantially as set forth.

In testimony whereof, I have hereunto set my hand and aifixed my seal,in the presence of two attesting witnesses.
